WebLatencyStrategy. To enable this property for fixed-point types, set Function as sin , cos, sincos , cos+jsin, or atan2 and Approximation method as CORDIC. Specify whether to map the blocks in your design to MAX , CUSTOM, or ZERO latency for fixed-point and floating-point types. The default is MAX. WebAug 13, 2012 · extern _ARMABI double atan2(double /*y*/, double /*x*/); Is there a lib or function I can include that has the function arctan implemented? Or is there an alternative function to calculate angles from accelerometer? I need full 3-axis calibration of the angles. Edit: I was hoping to avoid a table full of pre-calculated values.
